  Current APIs to set range on auras modifies both the
aura range limits in software and pool range limits
in NPA hardware.

Newly added ROC APIs allow to set/get aura range limits
in software alone without modifying hardware.

The existing aura range set functionality has been moved
as a pool range set API.
